Xocó (Chocó, Shokó) is an extinct and poorly attested language or languages of Brazil that is not known to be related to other languages. It is known from three populations: Xokó (Chocó) in Sergipe, Kariri-Xocó (Kariri-Shoko, Cariri-Chocó) in Alagoas, and Xukuru-Kariri (Xucuru-Kariri, Xucuru-Cariri) in Alagoas. It is not clear if these were one language or three.
